| 摘 要： | 排水沟渠是农业区重要的水利工程,其排水功能更是农业安全生产的重要保障,然而农田排水沟渠的生态功能未得到足够重视。随着农业面源污染研究的深入,农田排水沟渠在控制磷面源污染上的作用日益引起人们的关注。针对农业面源磷污染控制问题,简要归纳总结了农田沟渠系统对磷面源污染的迁移转化机理及影响因素,并在此基础上,探讨了排水沟渠控制磷污染的措施,以期为农业面源污染控制和管理提供参考。

| Abstract: | The function of drainage ditches is important for the agricultural production.However,little attention has been paid to ecological functions of agricultural drainage ditches.In recent years,many researches have been developed in the agricultural non-point source pollution,and focused on the effects of drainage ditches reducing phosphorus from agricultural non-point source pollution.This paper reviews the purification mechanism,influencing factors and controlling measures of agricultural ditch systems for phosphorus from non-point source pollution.The purpose is to manage and control agricultural non-point source pollution.Further researches should be conducted on the migration and transformation of phosphorus in the multilevel drainage ditches,enhancing control measures and applying ditch ecosystem effectively. |
